Mobile Phone Use in a DevelopingCountry: A Malaysian EmpiricalStudy
Paul H.P. Yeow, Yee Yen Yuen, and Regina Connolly
ON the streets of major Asian cities such as Shanghai
and Tokyo consumer use of mobile telephones is com-
monplace. In addition to being a mode of communi-
cation, mobile telephones are often the primary method by
which students and working adults access the Internet and for
many it would be simply unimaginable to live without this tech-
nology. In Malaysia, as of May 2006, there were 16.2 million
mobile phone users registered with the five digital networks,
with the majority of these located in major cities such as Kuala
Lumpur and Malacca. Studies of the profiles of these individuals
have shown that they are likely to have full-time jobs and high
incomes and tend to make more weekly phone calls compared to
those who do not use mobile phones.
Although the literature indicates that numerous studies have
been conducted on the influence, perception, and use of modern
technologies in urban daily life, such as Yeow et al.’s study
which focused on user acceptance of a multipurpose smart identity
card in cities in Malaysia, and other studies by Coates; Brown,
Balepur, and Mokhtarian; Fernandez-Maldonado; Firmino;
Ghere and Rismiller; Huh and Kim; Pons-Novell and Viladecans-
Marsal; and Loo, which have investigated the factors that affect
widespread adoption of the Internet and other information
communication technologies, few have examined the negative

aspects of mobile phone usage in urban areas. Such information is
particularly important for urban planners and policy makers in
their efforts to create a conducive and user-friendly environment
for daily mobile phone communications. For example, although
Townsend’s study highlighted the role of mobile telephones in
eliminating the spatial and temporal constraints of human com-
munications, quickening the pace of urban life and increasing
the formation of new decentralized information networks of
urban systems, it does not reveal crucial problems affecting
overall mobile phone satisfaction. Moreover, the limited number
of studies which have focused on negative aspects of technology
adoption, such as the House of Commons Select Committee
report, tend to be narrowly scoped. For example, that study
merely concentrated on the design and placement of antenna
towers in urban areas to meet increasing demands without provid-
ing guidance on how to mitigate the health risks of prolonged
mobile phone use. Other studies, which have examined negative
aspects of mobile phone use have been similarly narrowly
focused and location-specific, for example examining the negative
impact of mobile phone use in cars or public places without
measuring the positive effects, e.g., communication with family
and friends, and family coordination. This study redresses that
imbalance by providing a comprehensive investigation of the
factors influencing citizen’s satisfaction and dissatisfaction with
daily mobile phone use. It suggests a number of solutions to
resolve current mobile phone usage problems. Previous studies
have focused on citizens’ mobile phone dependency in general
without the use of statistical analysis to verify the validity of the
constructs being measured or the relationships between those con-
structs. This study, on the other hand, examines the interrelation-
ships of all tested variables using factor analysis and stepwise
multiple linear regression. It provides a platform for future
research by assisting specialists such as ergonomists, health and
safety practitioners, and academics/researchers in identifying
common mobile-phone use problems before conducting follow-
up studies such as actual laboratory experiments to address those
problems. From a practitioner perspective, this study provides
insights that will be of benefit to central and local government
bodies (who act as city planners) in their efforts to manage and
improve the quality of mobile phone use in large cities such as
Kuala Lumpur and Malacca in collaboration with local telecom-
munication companies. In addition, the findings of this study
provide mobile phone designers/manufacturers with an improved

understanding of end-users’ concerns and thus assist them in their
efforts to design contemporary mobile phones that provide a more
satisfactory response to consumers’ needs.
Literature Review
In the literature, the Overall Mobile Phone Satisfaction (OMPS)
construct has been described as “the consumer’s post-mobile
phone consumption evaluative response or judgment that a
mobile phone provides a pleasurable level of consumption-
related fulfillment, including levels of under or over-fulfillment.”
The literature also indicates that OMPS is significantly influenced
by six Mobile Phone Usage Factors (MPUFs). These factors are
now discussed in more detail.
Peer ChattingThe first of these factors, peer chatting, is one of the most obvious
reasons for mobile phone use. Studies indicate that consumers’
preferred mode for informal communication with their friends is
the mobile phone. Moreover, the ability to use short messaging
service (SMS) functionality to alert friends to an interesting item
of news, while saving the details for a phone call or meeting has
been shown to contribute to an increase in user satisfaction with
mobile phones as a communication medium. A recent study
showed that criticism and negative evaluations account for only
5 percent of mobile phone peer chatting time, asking for or
giving advice on how to handle social situations also accounts
for only 5 percent, and the bulk of mobile phone conversations
focus on “who is doing what with whom” and personal social
experiences. Mobile phones are, therefore, an essential facilitator
of these social exchanges.
Family CoordinationThe increased ability that mobile phone use confers on an individ-
ual to coordinate with other members of the family is a significant
but often overlooked factor that increases satisfaction with this
technology. For example, research by Rakow and Navarro has
identified an increase in working adults’ OMPS related to their
ability to use mobile phone communications to contact and super-
vise their children when business commitments delay their return
home. Clearly, parental anxiety is reduced when parents know that

they can contact and monitor their children regardless of location
and as mobile phone conversation is a direct mouth-to-ear connec-
tion, it provides a perfect channel for direct, intense, family com-
munication between parents and children when the parents are not
at home.
Social InterruptionHowever, it is acknowledged that not all aspects of mobile
phone use are positive and contribute towards consumer satisfac-
tion with the technology. For example, from the viewpoint of
most workers, to receive incoming mobile phone calls and
SMS during an important meeting or a complex/concurrenttask is disruptive. Similarly, most people in meetings and
lecture rooms are disturbed by the presence of loud mobile
phone calls and express their displeasure non-verbally by termi-
nating their social interaction immediately or by redirecting their
gaze away from the caller. Frequent mobile phone interruptions
have also been shown to lead to lower decision accuracy and
the need for longer decision-making time. In addition, Cutrell,
Czerwinski and Horvitz discovered that hearing a noisy mobile
phone ringer increases stress and reduces productivity. The
need to temporarily exit from a concurrent meeting in order
to answer a mobile phone call can lead to task performance
deterioration because it may disrupt the process of brainstorming
and formation of new ideas. In Madrid, students (and lecturers)
always answer a call, even if they have to leave the classroom
because they think that it is rude to let a call go unanswered.
However, answering phone calls immediately during class time
is likely to affect their concentration and academic performance.
Public DisturbanceA second negative factor relates to the noise pollution that results
from increased usage of mobile phone communications. For
example, studies have shown that mobile phone use in public
locations irritates 74 percent of bystanders, primarily because
the speaker was speaking loudly or because the bystanders were
forced to overhear the mobile phone conversation when trapped
in a confined area like a bus or train. Being forced to hear these
conversations distracts the thoughts of surrounding people who
feel awkward and embarrassed at overhearing personal issues
being discussed. Loud mobile phone conversations may make
people feel that, “If I can hear what other people are saying, in

another situation others would also be able to hear what I am
saying,” which is an uncomfortable reflection of their own conver-
sations being overheard when they use mobile phones in public
places. A factor that contributes to the difficulty of engaging
in mobile phone communication in public places relates to the
background noise caused by the location of the mobile phone
caller and receiver. As discovered by Farah, Monk et al., and
Terrel and Hammel, users need to speak louder on mobile
phones compared with face-to-face communications, since the
low sound quality of mobile phones makes it difficult for users
to hear and understand their counterparts over the phone.
When users are forced to speak loudly through the phone (as a
compensational strategy for the difficulties of hearing due to
background noise or perhaps poor sound quality), it results in
increased public disturbance. Clearly, the advantage of anytime,
anywhere communication that mobile phones confer on end
users contrasts with the irritation and disturbance of those situated
near the end user.
Radio-Frequency Radiation Health EffectsStudies have shown that consumer concerns regarding the occur-
rence of insomnia, brain tumors, dizziness, headache, nausea,
and fatigue due to excessive mobile phone radio-frequency radi-
ation exposure are increasing. Despite the fact that studies to
date have failed to identify a significant link between the length
of mobile phone conversations and possible health hazards, and
despite the fact that levels of exposure have been shown to gener-
ally reduce with increasing distance from the source, consumer
concerns remain significant and are likely to inhibit full adoption
of mobile phone technology.
Road AccidentsAnother disadvantage of mobile phone use relates to the use of the
technology by car drivers. Studies have shown that individuals
who use mobile phones while driving their cars are less capable
of maintaining a constant speed and keeping a safe distance
from the car in front of them. In addition, their tendency to fail
to notice road-warning signs is significantly higher when com-
pared to those who do not use mobile phones when driving. For
example, drivers’ responses to traffic signals have been shown to
be significantly slower and drivers tend to miss more road sign-
boards while using either a hand-held or hands-free phone. In

contrast, listening to the radio or a tape does not significantly
deteriorate driving performance. Therefore, it can be concluded
that the driver’s distraction results from his or her active engage-
ment in mobile phone conversations rather than carrying a phone
or listening to the radio in the car.
These six factors that have been identified in the literature,
two of which are positive and four of which are negative,
will form the main basis of this study’s research framework.
They will be treated as independent variables. The significance
of these variables and their predictive influence on the
dependent variable, overall mobile phone satisfaction in Malaysia,
will be examined in detail. Figure 1 outlines the research
framework.

Methodology
In order to test the relationship between the independent and
dependent variables, a sample of three hundred students and
working adults, all of whom were aged between 16 and 55 years
old, were selected as respondents for this study. This sample
was drawn from two urban areas in Malaysia, i.e. Malacca and
Kuala Lumpur, which comprise approximately 50,000 and 1.62
million users, respectively, out of the total 16.2 million mobile
phone users in Malaysia. Malacca is a small city and Kuala
Lumpur is the largest city in Malaysia.
The measurement instrument was developed and pilot-tested
before being distributed to the respondents. Thirty students and 30
working adults were selected as respondents for the pilot test.
These respondents were invited to comment on the items that
they considered as deserving of modification, clarification, or
removal. Their views on the appropriate length of the question-
naire were also examined and taken into consideration during
the preparation of the final survey questionnaire. The results of
the pilot study were analyzed and have previously been presented
in Yeow and Yuen. The final measurement instrument was com-
posed of 27 questions on the six mobile phone use factors
(MPUFs). Of these, three questions examined mobile phone use
for the purpose of peer chatting, three questions related to
mobile phone use for the purpose of family coordination, five
questions related to mobile phone social interruption, three ques-
tions related to public disturbance, ten questions related to
mobile phone radio-frequency radiation health concerns, and
three questions related to road accidents related to mobile phone
use. In addition, a question on Overall Mobile Phone Satisfaction
(OMPS) was included in this measurement instrument. The ques-
tions were rated using a 5-point Semantic Differential Scale
anchored by 1 (Strong dissatisfaction), 2 (Dissatisfied), 3
(Neutral), 4 (Satisfied), and 5 (Strong satisfaction). The research
data were then analyzed using parametric statistical tests including
factor analysis and stepwise multiple linear regression.
Half of the respondents in this study were students and the
other half were working adults as indicated in Table 1. Forty-
two percent of the respondents were males and 58.0 percent
were females, 59.3 percent were Malays, 27.3 percent were
Chinese and 13.3 percent were Indians. Half the respondents
were in the 21 to 30 age bracket while 18.4 percent of the respon-
dents were more than 30 years of age.

Results
The results of the factor analysis on the 27 attributes included in
the survey questionnaire are indicated in Table 2. The attributes
can be grouped into six factors, Radio-Frequency Radiation
Health Effects, Social Interruption, Peer Chatting, Public
Disturbance, Family Coordination, and Road Accidents (with an
eigenvalue greater than 1.00, 73.72 percent of the variance
explained). The reliability of each factor was tested using
Cronbach’s Alpha coefficient and the results, which are shown
in Table 2, indicate a high internal consistency in the respondents’
answers (with Alpha coefficients of greater than 0.6). Conse-
quently, no items were removed.
A stepwise multiple linear regression analysis was used to
confirm the criterion validity of this study by establishing relation-
ships between the independent variables (MPUFs) and dependent
variable (OMPS). From the results outlined in Table 3, it can be
seen that the adjusted multiple coefficient of determination
(adjusted R2) clearly explains 51.4 percent of the variance associ-
ated with OMPS, which is considered as highly significant. The
F-ratio is also highly significant at 37.289, confirming that
the variables make a significant contribution to the fitness of the
regression model. The results indicate that Peer Chatting and
Family Coordination factors positively affect OMPS while
Radio-Frequency Radiation Health Effects, Public Disturbance,
Road Accidents and Social Interruption factors negatively affect
OMPS. All six significant MPUFs were found to have very low

Variance Inflation Factor (VIF) values (,10), thus confirming that
the independent variables tested in this study are not highly corre-
lated or inter-related.
Discussion
Factor AnalysisIn this study, a multivariate factor analysis, one of the most power-
ful methods of testing construct validity, was used to develop
factors to measure the degree to which the questionnaire relates
to expectations formed from theoretical or hypothetical constructs.
All attributes in the questionnaire were grouped into six indepen-
dent factors with no attributes dropped and the total variance of
73.72 percent indicates that the questionnaire has been well
designed and is valid (Table 2). The results for each of these
factors are now discussed in more detail.
The Family Coordination factor comprised a number of items
that measured coordination of family activities and maintenance of
the family relationship. (See Table 2.) The result for this factor
confirms that working parents view mobile phones as being par-
ticularly useful tools in assisting them to organize significant
family activities, in maintaining relationships among family
members, and in helping them to perform time-consuming care-
giving roles when they cannot return home on time. This result
is consistent with the belief highlighted in the literature that
parents use mobile phones to keep in touch with their children
and to monitor their behavior during working hours.
The Peer Chatting factor consisted of items that measured
mobile phone use for the purpose of chatty talks and experience-
sharing with friends. (See Table 2.) The results obtained for
this factor confirms findings from the literature that the mobile
phone provides autonomy to discuss any affairs without parental
control. It, therefore, facilitates teenagers and working adults
who wish to talk about personal matters, relationships, and
secrets.
The Social Interruption factor encompassed items that
measure interruption of social activities (e.g., face-to-face conver-
sations, meetings, or lectures) resulting from a ringing mobile
phone. (See Table 2.) The results obtained for this factor
confirm the findings of a previous study that found that mobile
phone users tend to interrupt meetings or lectures when they
leave their mobile phones switched on all the time.

The Public Disturbance factor included items that measured
mobile phone intrusion as experienced by nearby people in
public settings. (See Table 2.) The study finding confirms the find-
ings of previous studies, which indicated that a loud mobile phone
ringer and loud mobile phone communication are considered to
seriously disrupt the privacy of others in public places. Despite
this fact, most users remain indifferent towards the need of the
public for peace and quiet, indicated by the fact that they do not
ensure that their mobile phones are switched off or reverted to
silent mode when they are in public places.
The Radio-Frequency Health factor comprised items that
measured perceived health hazards resulting from prolonged
mobile phone use. (See Table 2.) The findings of this study are
consistent with the results of previous studies that show that con-
sumers have significant concerns regarding the possibility that
adverse health effects like insomnia, headache, dizziness,
nausea, and leukemia may be caused by repeated and acute
exposure to mobile phone radio-frequency radiation.
In this study, the Road Accident factor included items that
measured a road crash and other road errors resulting from
mobile phone use while driving. (See Table 2.) The results for
this factor confirm that mobile phone use in a car is perceived to
slow down the driver’s reactions, divert his or her attention, and
lead to an increase in road accidents—a result that is consistent
with the findings of previous studies.
Key Mobile Phone Usage Factors (MPUFs) That AffectOverall Mobile Phone Satisfaction (OMPS) PositivelyThe study results show that the Peer Chatting factor positively
affects OMPS as it has the highest Standardized Coefficient Beta
value of .284 and the highest t value of 5.71. (See Table 3.)
Regular mobile phone chatting with friends fascinates Malaysians
and increases their OMPS. Fox, Hodge, and Townsend discovered
that in fast-paced and fragmented modern cities where friends are
scattered, and even if their friends live nearby, individuals are
often too busy or too tired to visit. Therefore, mobile phones
play a vital role in social bonding. Many teenagers have dozens
of friends, with whom they remain in contact by chatting via the
mobile phone and by exchanging text messages. Studies have
shown that conducting evaluative talk or gossip about a person
who is not present (e.g., celebrities and other public figure such
as royals and politicians) enables the development of social
skills, reinforces shared values, resolves conflicts, and builds

support networks. Mobile phones facilitate frequent passing
exchanges thus enabling the user to keep up with the small
details of what is going on in people’s lives and ensure that indi-
viduals are connected to their social and support networks. It has
been shown in experiments that the mutual grooming of primates
stimulates the production of endorphins, natural painkilling
opiates for the body. This makes the primates feel relaxed,
reduces their heart rate, and eliminates other signs of stress. It
is, therefore, conceivable that the “vocal grooming” of humans
via mobile phone chatting may have similar effects in alleviating
the stress of modern, fragmented lifestyles through enabling fre-
quent, spontaneous, casual communication to take place at
anytime and anyplace.
Family Coordination is the second crucial Mobile Phone
Usage Factor that is positively associated with OMPS as indicated
in Table 3. When there is an increase in mobile phone use in dis-
cussing and coordinating daily family activities, it will sub-
sequently boost OMPS. Rakow and Navarro found that mobile
phones are often used in organizing schedules to transport children
to various events such as tutoring or co-curricula activities. The
efficiency of daily “pick up” activities increases when working
parents can instantly call their children to meet them at a desig-
nated venue without wasting time anxiously looking for them.
Since mobile phone ownership is common among Malaysian
urban students and working adults, it facilitates working parents
in checking where their children are and in monitoring what
they are doing, thereby increasing their satisfaction with mobile
technology.
Self-esteem can be built through good family communi-
cation. A child knows that he is loved and realizes his capability
through daily communication with family members. Sound
nurturing family communication helps a child to build self-confi-
dence, points out skills and strengths, and makes a child aware of
his worth. Parents in big cities can frequently be too busy to com-
municate with their child in a way that shows affection and affirms
their love. As a result, the childmay not receive adequate nurturing.
Within this context, the mobile phone provides the potential for
increased interaction between busy working parents and their
children. It offers working parents an opportunity to attend to
their children’s problems and improve parent-child understanding
when parents are away from home possibly during business trips.
Before the invention of the mobile phone, individuals who were in
transit could only use public phones to connect with stationary

individuals, but they themselves could not be contacted and could
not participate in immediate family discussions. Now, the mobile
phone allows for nearly continuous and ubiquitous communi-
cation, providing a greater degree of freedom for family
members, whether stationary or in transit, without losses in trans-
mission speed and reaction time. It helps in remembering birth-
days and anniversaries, organizing family gatherings, consoling
sick family members, and retelling family history to enforce and
strengthen the social integration of the family. In short, it can
act as a social nurturing tool.
The growing number of married women in the urban work-
force makes the ability to synchronize home and work increasingly
important. The mobile phone allows busy working women to sche-
dule and plan their office and family tasks in advance or to com-
plete their office tasks while at the same time communicating
with family members via their mobile phones. This greater
control over timing assists them in coordinating the demands of
all of their family members quickly without affecting their daily
working performance.
As children grow up and increase the time when they are
absent from the family home, the mobile phone helps to cushion
traumatic experiences or loneliness in foreign or unfamiliar
environments by keeping children connected to their parents.
Short Message Service (SMS) has become particularly popular
with individuals who tend to be reserved with other people.
Urban teenagers perceive SMS as a useful method to communicate
without having to voice feelings and thoughts directly. Perhaps the
demand of brevity in composing the SMS in the absence of the
face-to-face interaction encourages those who are shy to express
themselves and enables them to frankly communicate their home-
sickness and loneliness to family members when they are away
from home. It is also relatively certain that the SMS will be
received by the individual to whom it is sent, without somebody
else taking notice, in contrast with oral telephone calls, which
are completely unpredictable in terms of whether the family
member called will be at home or whether unwelcome third
parties may be present.
Key Mobile Phone Usage Factors (MPUFs) That AffectOverall Mobile Phone Satisfaction (OMPS) NegativelyNot all of this study’s findings are positive. The results in Table 3
show the Radio-Frequency Radiation Health factor to be the
strongest negative factor associated with OMPS with the

highest Standardized Coefficient Beta value of 2.442 and the
highest t value of -8.37. It, therefore, appears that an increase in
radio-frequency radiation health concerns will subsequently
reduce OMPS. It may be that the media coverage of mobile-
phone-related radio-frequency heath concerns has increased
citizens’ health concerns and awareness of this issue. Several
studies have shown that prolonged exposure to radio-frequency
radiation may result in insomnia, dizziness, headaches, and ear-
aches and it has been argued that radio-frequency radiation may
result in a “unilateral influence” on the vestibular system in the
middle ear and consequently affect users’ health. There are also
concerns about possible effects of radio-frequency radiation on
the brain when the mobile phone is conventionally held close to
the head. Although major telecommunications companies in
Malaysia such as Maxis frequently proclaim the safety of mobile
phone use issuing statements that the levels of mobile-phone-
related radio-frequency radiation are insufficient to cause
adverse health effects while being used, these statements clearly
remain unconvincing for the majority of mobile phone users in
this study.
Besides concern about personal health, Yeow and Yuen
found that Malaysian mobile phone users are also concerned
about the health of their friends and family members. According
to the Health Council of the Netherlands, the Independent
Expert Group on Mobile Phones, and the International Commis-
sion on Non-Ionizing Radiation Protection (ICNIRP), a portion
of the population such as elderly people, infants, and young chil-
dren are less tolerant of radio-frequency radiation exposure and
face elevated risks in experiencing mobile-phone-related health
problems due to potentially higher radiation sensitivity. Therefore,
more confirmative studies examining the radio-frequency radi-
ation tolerance level of these population groups are necessary if
the worries of mobile phone users are to be alleviated. Further-
more, mobile phone users in Malaysia are also possibly unclear
about mobile phone radio-frequency radiation exposure limits
due to insufficient information on the official web sites of govern-
ment agencies such as those of the Ministry of Health and of the
MalaysianCommunicationandMultimediaCommission (MCMC).
This contrasts with other countries such as England, where
national guidelines on radio-frequency radiation exposure have
been issued by the ICNIRP. In addition, there is a standard
testing procedure in the United Kingdom for the measurement of
the specific energy absorption rate (SAR) of different mobile

phones (SAR is the average mobile phone radio-frequency
radiation exposure time on a specified mass of tissue or tissue
region). However, in Malaysia, there are currently no widely
adopted radio-frequency radiation exposure limit guidelines or
SAR testing method. It is also difficult for mobile phone users to
acquire information relating to the SAR measurement due to
limited publicity of such information. Different mobile phones
cannot be compared at the point of purchase nor can a customer
take preventive measures to mitigate excessive radio-frequency
radiation because there is not enough information available.
The Public Disturbance factor is the second factor that is
negatively associated with OMPS, with a Standardized Coefficient
Beta value of 2.222 and t-value of 24.34. (See Table 3.) In large
fragmented cities, women and men of all ages make and receive
mobile phone calls on the streets or even in places where mobile
phone use is publicly banned such as in cinemas, concert halls,
classrooms, and planes. These individuals maintain that any dis-
turbance resulting from the use of their mobile phones is of far
less importance than their need to answer the phone call. This atti-
tude of indifference results in users speaking on their mobile
phones in public places without any consideration of the disturb-
ance that may cause to the people nearby.
In Malaysia, there is currently no national law to restrict users
from answering mobile phone calls at public places. Conse-
quently, on streets, in cinemas, shopping complexes, and restau-
rants, it is commonplace to find someone speaking loudly on her
mobile phone. The government, mobile phone designers, and tele-
communications companies have yet to determine ways to
improve the sound quality of mobile phone receivers and restrict
loud mobile phone calls at designated public places to protect
the public from mobile phone disturbance. Until such interven-
tions take place, the problem is likely to persist.
The third MPUF that is negatively associated with OMPS is
the Road Accident factor. It has a Standardized Coefficient Beta
value of 2.210 and t value of 23.99. An increase in Road Acci-
dents will subsequently lower OMPS. (See Table 3.) Research by
Demas and Rosenthal Injury-Attorneys discovered that 87 percent
of users believed that mobile phones impair their ability to drive.
Hand-held or hands-free mobile phone use in cars possibly
reduces the driver’s awareness and ability to detect and
respond to potential dangers on the road such as bumps, barri-
cades, carts, and branches. Dialing a telephone number in city
traffic has been shown to significantly impair steering wheel

movements. Drivers experience a heavier mental workload due to
the need to attend to concurrent mobile phone tasks in the car,
which may lead to more road accidents. In 2004, the number of
Malaysians caught using their mobile phones without hands-free
kits were 47,247 (with an average of 129 people being caught
daily). The summonses issued increased by 6,002 copies from
41,245 copies in the previous year. Perhaps implementation
flaws in the road safety demerit point system make drivers feel
that they can easily escape being punished. According to MCA,
the main weakness in the road safety demerit point system is
that the point will only be deducted when a motorist pays his
traffic summons or court fines. If the motorist chooses to ignore
the summons, he will remain unaffected by the demerit system.
Drivers’ perceptions that they can escape from the penalties
associated with the use of mobile phones while driving can be
detrimental as it can result in the continuance of reckless driving.
Another factor contributing to the escalation of mobile phone
summons relates to the lack of road safety concepts or familiarity
with road regulations. Many drivers do not realize the danger of
pulling over to the road shoulder or emergency lane to answer a
phone call and do not think of it as a serious offense. Despite
many road safety campaigns to improve mobile phone awareness,
the results remain unsatisfactory. Although the use of mobile
phones with hands-free kits is allowed in Malaysia, Brookhuis
and De Waard and the World Health Organization recommend
that both hand-held and hands-free phones should be banned
because even if the drivers are using a hands-free mobile phone,
they still need to divert part of their attention to manipulate the
phone while operating the vehicle and respond to the constantly
changing road and traffic conditions. This can impair their ability
to maintain car speed and respond to changing road conditions.
The Social Interruption factor is the fourth factor that is nega-
tively associated with OMPS. It has a Standardized Coefficient
Beta value of 2.130 and t value of 22.63. (See Table 3.) Mobile
phone social interruption is a common problem for urban users
since they tend to keep their phones switched on all the time.
The Malaysian Chinese Association discovered that 57 percent
of Malaysians did not have a fixed-line phone and relied entirely
on mobile phones to keep in touch with family and friends. This
high reliance on mobile phones increases the chance that the
social activities of users will be interrupted by incoming mobile
phone calls and SMS, which are more difficult to control than out-
going phone calls and SMS. For example, when the mobile phone

rings, users face a dilemma of choosing to answer the phone
immediately or ignoring the call and continuing their social inter-
action with co-located friends. In cities such as London and Paris,
users choose to quickly pause or withdraw from their social inter-
action in order to answer the phone call. The face-to-face inter-
action is interrupted, and users and their co-located friends act
as if they are not together anymore. As a result, they may experi-
ence difficulty in resuming their social activities subsequent to
answering the call.
Users who conduct loud mobile phone conversations in meet-
ings and classes may have a low willingness to pay attention to
other co-located people’s needs relative to their own real-time
mobile phone communication needs. They possibly have a low
self-monitoring ability, prefer to act according their own emotions,
and do not control their mobile phone use despite its situational
inappropriateness. Perhaps they do not notice the tension and
dissatisfaction caused by noisy mobile phone ring tones, which
distract the attention of their co-located partners.
Recommendations
Suggestions to Promote Mobile Phone Peer ChattingSince urban mobile phone users show a high interest in peer
chatting by ranking it as the most important factor affecting
OMPS, telecommunication companies should promote economi-
cal mobile phone calls, SMS, and Wireless Application Protocol
(WAP) for the benefit of users with lower incomes. The network
service coverage areas should be expanded to facilitate nationwide
and international peer chatting. Some free talk time could be given
as promotion items and campaigns to promote chatting interests
could be organized. Users with good chatting experiences could
be invited to share in talk shows. All these programs are beneficial
to telecommunication companies as they help to increase their
revenue and broaden their market share.
Current WAP chatting services are considered cumbersome
and frustrating because of poor connection links and innumerable
keystrokes. To encourage WAP chatting, mobile phone designers/manufacturers should ensure that the WAP page is well structured
via clear category links and requiring fewer keystrokes. In order to
sustain better mobile phone call chatting, the sound quality of the
mobile phone should be improved and background noise elimi-
nated as much as possible.

Future studies to verify the most-acclaimed stress alleviation
benefit of mobile phone chatting should be jointly conducted by
ergonomists and health practitioners. If it is proven in future lab-
oratory experiments that mobile phone chatting helps in effec-
tively reducing work-related stress and boosting body immunity,
blue and white collar workers in the government and private
sectors should be given moderate freedom of mobile phone chat-
ting in their workplaces (on the basis that it would not reduce pro-
ductivity) to ensure that workers are able to lead healthy lives.
Telecommunications companies could then highlight the benefits
of mobile phone chatting through advertisements, brochures, and
pamphlets.
To prevent money and time being wasted on low-value
mobile phone chatting, local and central government should
advise citizens to conduct constructive mobile phone discussions
with friends. Users should be made aware of the danger of reveal-
ing their personal information such as e-mail addresses, home
addresses, or landline phone numbers or arranging face-to-face
meetings with mobile phone acquaintances since newly known
people on the other end of the phone may not be as honest as
they portray themselves to be. Mass media should highlight
mobile phone crimes in order to create greater user awareness of
the need for circumspection when using the mobile phone.
Citizens in well-developed, fast-paced modern societies such
as Japan experience high stress levels, which possibly contributes
to the high suicide rate in recent years. In our fragmented modern
world, social bonding becomes even more important but also more
difficult because people no longer live in the kind of small, close-
knit communities that are conducive to such bonding. Mobile
phone chatting restores urban people’s sense of connection and
community, and provides an antidote to the pressures and alien-
ation of modern life. Therefore, it should be promoted widely in
big cities of both developed and developing countries.
Suggestions to Promote Mobile Phone Family CoordinationSince self-esteem and self-confidence can be built through good
family communication, the Ministry of Women, Social, and
Family Development, telecommunications companies and mass
media should accentuate the benefit of mobile phones for
regular communication with family members. This can be
achieved through seminars, campaigns, advertisements, and even
television dramas. Parents should be encouraged to use mobile
phones more often to check their children’s whereabouts and

ensure that they are safe. Working parents should be encouraged to
listen to their family members’ problems and share life experiences
with family members through the use of mobile phones. Intro-
verted working adults who are shy and have difficulty expressing
their homesickness during business trips may also be encouraged
to make use of the SMS and WAP service to communicate with
their families. Such effects may certainly boost the role of mobile
phones as a useful tool for social cohesion and family bonding.
It is common for married women in developed countries such
as the United States and Australia to participate in the labor force.
Since mobile phones allow working parents to conveniently cater
to the needs of their children during working hours and during
business trips, the benefits of mobile phone use for the purpose
of family bonding should also be promoted in the developing
countries under discussion.
Suggestions to Reduce Health Concerns Associated withMobile Phone Radio-Frequency RadiationDesigners and manufacturers should design the mobile phone to
minimize users’ radio-frequency radiation exposure at the level
necessary for the device to function. Watchful examination of
radio-frequency radiation exposure should be carried out in com-
pliance with the existing standards by the Health Council of the
Netherlands and the International Commission on Non-Ionizing
Radiation Protection to ensure that only qualified and safe
mobile phones are introduced into the market. SMS and WAP
use should be promoted through advertisements, seminars, and
conferences since radio-frequency radiation exposure levels
while using the SMS and WAP services are significantly lower
than those of mobile phone calls. Users should also be educated
to minimize and shorten the period of time they spend engaging
in mobile phone calls especially in areas where the signal is
poor because a weak signal from the base station causes handsets
to increase their broadcasting power and radiation exposure.
The Ministry of Health and the Malaysian Communications
and Multimedia Commission should work closely with ergono-
mists and health and safety practitioners to set up studies on the
general health complaints of mobile phone users. Local laboratory
research should be conducted to determine whether those who use
mobile phones for longer periods experience a higher health threat
compared with those who use them for shorter periods. The pro-
gress of the research should be closely monitored and the findings
should be disclosed upon completion. Citizens who need to make

numerous prolonged daily mobile phone calls for unavoidable
social relations maintenance purposes should be educated to alter-
nate between using both ears throughout the conversation to distri-
bute stress more evenly, and to give each ear a chance to rest.
Users should also be taught to not put their phones too near their
heads when making or receiving a mobile phone call. The
maximum radio-frequency radiation exposure limits should be
set for all mobile phones and the methods of measuring, minimiz-
ing, and monitoring radio-frequency radiation exposure should be
announced through media mass, seminars, and conferences to alle-
viate health concerns. Telecommunication companies should
ensure that accurate and understandable radio-frequency radiation
information is readily accessible to consumers at the point of sale
and on companies’ web sites to facilitate comparisons and evalu-
ations on the safety of different types of mobile phones.
The proliferation of mobile phone use in cities in China such
as Shanghai and Beijing may increase the possibility of users suf-
fering from adverse health problems. Laboratory research should
be conducted in those cities to verify whether frequent mobile
phone use carries a higher health threat. All the abovementioned
prevention measures should be taken by practitioners to protect
the health of mobile phone users.
Suggestions to Reduce Mobile Phone Public DisturbanceKopomaa stated that “the mobile phone was not only adapted to
our way of life, but our way of life was changed by it as well.”
The lives of urban dwellers are very different from the lives
they had before mobile phones. They can communicate and be
communicated with 24 hours a day, and personal contacts can
be conducted at any time, anywhere, including public places.
Mobile phone public disturbance is not unique to Malaysia. In
other big cities worldwide (e.g., Shanghai, Hong Kong, Cairo,
and Tokyo), citizens are disturbed by noisy mobile phone conver-
sations in public places. Therefore, the authors believe that the fol-
lowing recommendations can be applied not only by local
practitioners but also by practitioners all over the world to effec-
tively minimize mobile phone public disturbances in cities.
Soothing mobile phone ring tones should be introduced to the
urban community to mitigate public disturbance of mobile phones.
The sound quality of mobile phones needs to be improved in
order to keep users from having to raise their voices in public
places. To promote a courtesy culture, mobile phone users
should be educated to apologize to bystanders before conducting

a phone conversation and to lower their voices during the conver-
sation out of respect for bystanders. Mobile phone call use should
be prohibited in public places that require high concentration such
as cinemas, libraries, and churches, and all users should be
required to switch their phones to voice mail services and silent
mode in these places. Signal jamming devices could be introduced
in these places to ensure that no calls can be received or made.
Suggestions to Reduce Mobile Phone Social InterruptionBoth students and working adults should be advised to turn their
phones into silent or vibrating mode if they insist on switching
on their mobile phones during meetings or lectures to prevent
the noisy mobile phone ringer from interrupting the flow of meet-
ings or lectures. SMS should be introduced as an alternative
method of response to reduce social interruption in meeting
rooms. In circumstances where detailed mobile phone conversa-
tions are needed, users should completely leave their concurrent
social activities and keep their mobile phone calls short to mini-
mize the adverse effects of social interruption. Otherwise, they
should be advised to switch off their phones or direct the incoming
calls to voice mail services.
Since users in London and Paris also experience similar
social interruption problems when they keep their phones switched
on all the time, the abovementioned recommendations also apply
to practitioners in European cities where intensive seminars and
campaigns should be organized to educate users on when and
where is appropriate to engage in mobile phone conversations.
Suggestions to Reduce Mobile Phone-Related Road AccidentsAs a preventive and precautionary measure against mobile-phone-
related road accidents, health and safety practitioners should
advise users to initiate their mobile phone calls, SMS, and WAP
service only when their vehicle is parked in a parking area. For
an unexpected incoming call, users should be taught to make a
prudent judgment in choosing where to stop the vehicle to
receive an incoming call. They should be made aware that while
it is offensive, it is also very dangerous to pull over onto the
road shoulder or emergency lane to answer a phone call. When
it is inevitable that a driver must stop the vehicle to answer a
call, the driver should keep the call short to reduce the risk of
road accident. Schools should teach future drivers about the
danger of engaging in mobile phone conversations while driving.

Information about mobile phone road accident casualties and
photographs of road accidents caused by mobile phone use should
be published on mass media as a reminder to drivers. In addition,
legislation should be enacted to impose stiffer punishments
against errant drivers who continue to use mobile phones while
driving, and enforcement personnel should be allowed to confiscate
mobile phones from such drivers. The use of hands-free car phone
kits should be banned since part of the drivers’ attention is diverted
when trying to manipulate the kits while operating the vehicle. All
mobile phone users should be made aware of the danger of hands-
free kits through seminars, talks, and advertisements.
Despite the fact that studies to date have failed to identify a
direct link between the rate of mobile phone adoptions and road
accidents, the abovementioned measures should be adopted by
policy makers in big cities with high mobile phone proliferation
to prevent loss of life due to driver negligence.
Limitations of the Study
The results of this study are generalizable only in relation to
Malaysian urban students and working adults. However, it is poss-
ible that they may also be applicable to urban mobile phone users
in other Asian and non-Asian countries. Whether this is the case
remains to be determined by future studies. Another study limit-
ation relates to the fact that citizens aged above 55 years are
outside the scope of this study due to their small percentage
(less than 20 percent) of mobile phone ownership. Finally, this
study did not examine the effects of demographic variables such
as gender, race, subject class (student or working adults), etc.
The effects of these variables were not examined in this paper
because of space constraints and because the stated objective
was to focus on a limited number of satisfaction and dissatisfaction
related constructs. However, the influence of these variables on
end users’ satisfaction responses will be presented in future papers.
Conclusion
This study examined the factors that influence consumer satisfac-
tion with mobile telephone use in Malaysia. The validity of the
study’s constructs, criterion, and content was confirmed. Construct
validity was verified through the factor analysis with a total

variance of 73.72 percent explained by all six independent factors.
Content validity was verified with the development of the
independent and dependent variables based on the definitions of
the constructs from various national and international literature,
while criterion validity was confirmed through the stepwise mul-
tiple linear regression analysis between dependent and indepen-
dent variables. The study findings show that an increase in
mobile phone peer chatting and family coordination will signifi-
cantly increase OMPS while an increase in mobile phone radio-
frequency radiation health concern, public disturbance, social
interruption, and road accidents will significantly decrease OMPS.
